CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 597,667, dated January 18 1898.

Application filed October 6,1897. Serial No. 654,242. (No model.)

To all whom it may concern:

Be it known that- I, CARL E. BAUER, a citizen of the United States, residing in Chicago, Cook county, Illinois, have-invented certain new and useful Improvements in Oar-Trucks, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention. has relation particularly to the construction of the truck side plates and the formation of the pedestal-jaws upon the ends of the same. In the construction of these side plates I utilize, preferably, a piece of (30111- mercial rolled iron of I-beam section. Each end of this piece of I-beam I out in a peculiar manner, (to be hereinafter particularly described,) shearing out certain portions of the web, so as to produce a forked or split end of a peculiar shape, the two parts of which I then bend and interlock in a novel manner to form the jaws. The shearing and bending are done in such a way as to bring the projecting flanges of the base or bottom of the I-beam around upon the inside of the pedestal adjacent to the journal-box, so as to form a guide and support therefor, and the projecting flanges upon the upper or top portion of the Lbeani are bent around, so as to form a stiffening and strengthening rib or flange upon the outside of the pedestal. The two split portions of the web which are left attached to the flange after the shearing operation are brought into position, so that one will overlap the other, and the two are rigidly secured together by a number of rivets. By overlapping the web portions of the split ends in the manner described I double the thickness and consequently also the strength of the web of the overhanging jaw. By the arrangement described I secure, further, a construction of side plate for truck-frames which may be easily made and at relatively small expense.

Further objects of my invention relate to other novel features of construction of the frame of the truck, among which may be mentioned the use of a cross tension-brace or a pair of the same to keep the truck from being twistedout of square.

The above, as well as such other objects as may hereinafter appear, I attain by the construction illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my improved truck. Fig. 2 is a partial plan view of the same. Fig. 3is an end view of the same. Fig. 4 is a vertical section taken on the line 4. 4. of Fig. 1. Fig. 5 is a horizontal section taken on the line 5 5 of Fig. 1. Fig. 6 is a diagrammatic representation of an I-beam ready to be made into my improved side plate. 7 represents the same after it has been cut to the required shape for bending. Fig. 8 represents the first stage of the bending operation. Fig. 9 represents the second stage of the bending operation, and Fig. 10 shows the completed jaw ready to receive the rivets.

In the formation of my improved truck I begin with the I-beam shown in Fig. 6. This I-beam I cut to the shape shown in Fig. 7, first drilling a hole at 11 and then shearing out the portions which it is desired to remove, so as to leave two forked or projecting ends 12 and 13, the portion 12 having the flanges 14 and the part 15 of the web and the portion 13 hav ing the flanges 16 and the part 17 of the web,

Fig.

the latter portion 13 being connected with the main part of the Lbeam by means of the flanges 16 only, the web being entirely-cut out around the lines 18, 19, and 20. I next bend the portion 12 upward and the part 21 downward, as shown in Fig. 8. The part 13 is now bent upward and back toward the part 21 and its outer extremity formed in the shape of the outer jaw of the pedestal, as shown in Fig. 9, the part 17 of the web of the Lbeam overlapping the part 21 and also the part 15 in the manner clearly shown in the figure last re ferred to.

The last step in the bending operation is to complete the formation of the jaw by bending the split portion 12 around to the position shown in Fig. 10, its web at 15 overlapping the web 17 of the split portion 13. In order to make a smooth bend along the line 19, a small filling-block 22 is inserted having a rounded under edge. A plurality of rivets 23 are now put through the two overlapping web portions of the bent parts 12 and 13, securing the same firmly together, as shown in Fig. 1.

A further examination of the drawings will show that I have obtained a pedestal which upon both its inner and outer face has a double projecting flange and which throughout its length has a double web rigidly held together by a number of rivets. This construction is easily and cheaply made and combines great strength with simplicity and durability.

To the flange 16, which now forms the inner part of the pedestal, I secure on opposite sides thereof the wearing-plates 23 in the manner shown in Figs. 4 and 5, and across the opened or lower end. of the pedestal I arrange the removable bolt 24. in the manner clearly shown in Fig. 1.

The side plates having been completed they are combined with the rest of the truck in the manner shown in Figs. 1 and 2, the main portion of the transom comprising the two channel-bars 25 and the plate 26.

Diagonally across the bottom of the central part of the truck I arrange a couple of tension-plates 27, hooked at their ends 28 around the outer flanges of the side plates, as shown in Fig. 1. These tension-plates being secured at their middle points by means of a rivet 29 form a simple and efficient brace against diagonal strains, which have a tendency to knock the truck-frame out of square. In place of these plates a couple of tension-rods can be used similarly arranged, if preferred.

WVhile I have described my invention as utilizing in the construction of the side plates a piece of commercial iron of I-beam section, it is perfectly evident that a channel or other equivalent shape, either commercial rolled or pressed, could be substituted for this I-beam, if desired without departing from the spirit of my improvements.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A car-truck side plate formed of a piece of metal having a web split at each end thereof and the two split portions of each end bent and overlapped to form a pedestal, substantially as shown and described.

2. A car-truck side plate formed of a piece of metal having its web split at each end, and the two-split portions at each end bent and overlapped to forin a pedestal, and secured together by rivets, substantially as shown and described.

3. A car-truck side plate composed of a piece of metal having a web and flanges, the web being split at each end and the two split portions bent with their web parts overlapping to form a pedestal, the flanges of the two split portions forming respectively flanges upon the inside and outside of the jaw, substantially as shown and described.

4. A car-truck side plate composed of a piece of metal having a web and flanges, the web being split at each end and the two split portions bent with their web parts overlapping, the flanges of the under split portion forming guides for the journal-box, substantially as described.

5. A car-truck side plate composed of a piece of metal having a web and flanges, the
